This invention relates to gas burners and Supports therefor, and hasspecial reference to burners for use in cooking ranges and stoves.

Objects of the invention are 'to provide pipes of improved constructionfor conducting the gas from the manifold to the burners, and improvedmeans for supporting the burners in one position for natural gas and inanother position for manufactured gas.

Other objects will appear from the following description, referencebeing made to the drawings in which A Fig. 1 is a plan view of a stovehaving my improved burners mounted therein. 1

A gas supply pipe 1 opens into a mani fold 2 at thefront of the stoveand has valve devices 3 for controlling and regulat ing the passage ofgas from the manifold 2 to burners which are in connectionwiththe pipes4and 5 each consists of a central hol- .low annular portion 8 and aseries of radial arms 9; opening from the annular portion 8. The annularportion 8 and the arms 9 have through their upper walls numerous gasoutletoningslilu Theburner '3' is ahollow chamr having through'its upper.wall a I and burner supportsnumber of gas outlet openings 11. Theseburners are all mounted in a proper order and relationship in a burnerbox frame 12 which is equipped with a suitable grid (not ral gas areknown and are not shown in the drawings.

Each pipe 4 is of increasing horizontal diameter from its front end toits union with one of the arms 9. Said pipe 4 is integrally united withand opens into the end and the under side of the arm 9. The insidehorizontal diameter of the pipe 4 at its union with the g arm 9 is thesame as the inside diameter of the Figs. 4 and 5 are top plan and sideeleva-' 5) away from .the upper wall of the burner arm 9 so that thevertical diameter of the arm '9 into which the pipe 4 opens increasesfrom the end inwardly. The upper wall of the pipe The subject matter-of.the present inven- 4 is a very slight distance below the upper. I

Thus the pipe 4 together with the burner arm 9 with which it isconnected forms an enlarged chamber, the horizontal'diameter of which isthe same as the horizontal diameter of the unitedportions of the pipe 4and the burner arm 9, and the vertical diameter of which chamber isgreater than the vertical diameter of the pipe 4. Moreover the verticaldiameter of the chamber 9'increases from its outer end toward .its innerend. l'his construction obtains'a superior mixture of air. and gas bycombustion of which greater heat is obtained than is obtained by the useof other types of burners "with which I am familiar.

Iii their construction and their connectio with the arms 9 of therespeetive burners the pipes are quite similar tothe construction andconnection of the pipes 4 with the burner arms 9. That is to say, thepipes 5 open into the ends and under; sides of the arms 9 with whichsaid pipes are connected, being of the same inside horizontal diameteras the arms 9 and of greater vertical diameter. The lower verticaldiameter of the pipe 5 and greater than any of the remaining burner arms9. These pipes 5 are provided with curved extensions 14 at theiriinnerends so that the burners in" connection with the pipes 4 may be made infront of the burners in connection with the pipes 5. In this arrangementthe pipes 5 are between the pipes 4.

When manufactured-gas is to be used as a fuel the burners are supportedin a higher position in the burner box when natural gas is used as afuel. The support for each of the rear burners comprises a bifurcatedsupporting bracket element 15, the ends of the arms of which areremovably seated in depressed portions of lugs 16 projecting from theinner side of'the rear portion of the burner box frame 12. Each of therear burners has an integral projection 17 from its rear arm forattachment with the adjacent supporting bracket to which it is securedby a stove bolt 18. When. natural gas is to be used as a fuel theprojection 17 is fastened on the under 'side of the supporting bracket15; and when manufactured gas is to be burned as a fuel the projection17 is fastened on the upper side of the supporting bracket15, therebysupporting the burners at a higher altitude in the burner box frame whenmanufactured gas is burned as a fuel than when natural gas is burned asa fuel.

The support for the burner 7 comprises an arm 19 which is fastened on alug 20 projecting from the adjacent side of the burner box frame 12 andsecured thereto by a stove bolt 21. When'natural gas is to be burned asa fuel the arm 19 is fastened on the under side of the supporting lug20; and when manufactured gas is to be burned as a fuel-said arm 19 isfastened on the upper side of the supporting lug 20, thereby supportingthe burner 7 at a higher altitude in the burner box than whenmanufactured gas is burned as a fuel.

The pipes 5. support the front burners. Each pipe 5 has an arm 22projecting laterally and provided with a hole 23. The rear arm of eachof the front burners is formed with a flange 24 and with a depending ing25. The lug 25 is for engagement in the hole 23. Rib 26 is integral withthe under side of the flange 24 and seats upon spaced lu s 27 on theupper side of the arm 22. e front ends of the ipes 4 and 5 are raised orlowered as the inner ends' of said pipes are raised or lowered toadaptthe burners for use of manufactured or natural gas. The specific meansfor supporting the front ends of these pipes in different altitudesconforming to the positions of the burners is not shown, as saidspecific supporting means for the front ends of said pipes is no part ofthe present invention. It will be understood, however, that thepositions of the pipes 4 and their burners are controlled by thepositions of the pipes 5.

The rear wall of the burner box has an outlet opening 28. A plate 29 ismounted for sliding movements in guides 30 and is capable of movementsin said guides to positions to open and to close the opening 28. Whennatural gas is burned as a fuel the opening 28 should be kept open inorder to permit the fumes to pass out and this con- (ition may bemaintained by keeping the plate 29. in open position. However, whenmanufactured gas is used, it may be unnecessary to keep the plate 29 inopen position all of the time.

This outlet opening 28 is above the wall 31 which forms the top wall ofan oven 32 and the bottom wall of the burner box. A connection for astove pipe is provided, the same comprising a pair of side walls 33, arear wall 34 and a flange 35. The flange 35 is attached to the rear wallof the stove by bolts 36 so that said walls33 and 34 form a passage toreceive the gas fumes dischar ed from the burner box through the opening28. A ring 37 is fastened to the upper end of the part comprising thewalls 33 and 34 by a bolt 38 and is provided with an upwardly extendedflange 39 on which the lower end of the stove pipe 40 is telescoped. Thestove pipe 40 seats upon the ring 37 and opens into a main stove pipe 41which, in the embodiment shown, constitutes a smoke outlet from anotherpart of the stove.

The plate 29 is freely movable to open and to closed positions along theguides 30 and is formed with a handle 42 whereby it may be convenientlymoved from one position to another. Accordingly, my invention is welldesigned to use natural gas or manufactured gas as fuels.

I From the.foregoing it must be apparent that I have produced a new andimproved type of burnercapable of satisfactory use in burning eithernatural gas or manu actured gas as fuels. These burners are assembled ina novel relationship to each other and to the cooperating stovestructure. This stove in which these burners are embodied is easilycapable of adjustment to burn either kind of fuel. The construction andarrangement may be varied within equivalent limits without departurefrom the nature and principle of the invention.

I claim I 1. In a gas stove, a hollow burner compris- 5 7 ing' hollowradial arms, in combination with a pipe for conducting gas to saidburner, said pipe being of increasing diameter from its outer end tointegral connection with one ofthe arms of said burner at the inner endof said pipe, the inside horizontal diameter of the pipe at itsconnection with said arm being equal to the inside horizontal diameterof the arm and thevertical diameter of the pipe at-its connection withsaid arm being greater k than the vertical diameter of the remainingarms of the burner, the upper wall of the 1 pipe at its connection withsaid burner arm eing s'lightl below theplan'e of the upper wall of saidurner arm and the lower wall of "the pipe inclining downwardly andinwardly throughout nearly the entire length of the burner arm. p 2. Ina gas stove, a hollow burner comprising hollow radial arms ofapproximately the same horizontal diameter, in combination with a pipefor conductinggas to said burner,

said pipe being of increasmg diameter from its outer end to integralconnection with one of the arms of said burner at the inner end, of saidpipe, the inside horizontal diameter of said pipe at the union thereofwith said arm of said burner being approximatel the same as the insidehorizontal diameter 0 said I arm.
